Freelancer profile translated to English.

Description

I am an experienced software developer with a focus on ERP systems, merchandise management, and EDI interfaces. For many years, I have been developing, expanding, and supporting business applications – primarily in the Xbase++ environment, complemented by SQL databases, reporting (including List & Label), and interfaces such as EDIFACT, XML, and CSV.

I support companies in the further development of existing systems as well as in the analysis of business requirements and their technical implementation. I have a good understanding of commercial processes and work in a structured, reliable, and solution-oriented manner.

In addition to classic application development, I have experience in support, troubleshooting, migrations, and collaboration with business departments and external partners.

Clients value my independent way of working, my calm and clear communication, and my ability to present complex issues understandably.

I work exclusively remotely and am open to both project-based and long-term collaborations.
